Optics Express

The original all-electronic, open-access optics journal, Optics Express (OpEx) is known for its rapid time to publication and high Impact Factor. OpEx publishes peer-reviewed articles that emphasize scientific and technology innovations in all aspects of optics and photonics.

The primary source of infrared radiation is heat—the radiation produced by the thermal motion of charged particles in matter, including the motion of the atoms and molecules in an object. The higher the temperature of an ...

Researchers at the Debye Institute for Nanomaterials Science, together with colleagues from the University of Twente and Thales Research and Technology (France), have found a non-invasive technique to measure the intensity ...

A team of engineers has developed a new acousto-optic device that can shape and steer beams of light at speeds never before achieved. The new technology will enable better optical devices to be made, such as holographs that ...

Detecting individual particles of light just got a bit more precise—by 74 picoseconds to be exact—thanks to advances in materials by National Institute of Standards and Technology (NIST) researchers and their colleagues ...

Researchers from North Carolina State University have developed a new tool for detecting and measuring the polarization of light based on a single spatial sampling of the light, rather than the multiple samples required by ...

By converting sunlight into usable energy, solar thermal devices could become an important part of a sustainable future. To that end, researchers have developed a new solar-light-absorbing surface that can have almost any ...

The intensity of artificial lighting has been shown to have a range of effects on our mood and our ability to concentrate. New research explores the color of lighting and its effect on our cognitive performance. The study, ...

Data centres such as the ones used by Google and Facebook are the fundamental backbone for a range of services and applications including cloud and fog computing, big data, Internet of Things (IoT), social networking, weather ...

Imagine watching a 3D movie on your smart phone and suddenly getting a headache or even feeling nauseous. Such viewer discomfort is one of the biggest obstacles preventing widespread application of 3D display technology – ...

Precise measurements of optical power enable activities from fiber-optic communications to laser manufacturing and biomedical imaging—anything requiring a reliable source of light. This situation calls for light-measuring ...
